How to use Random number generator
Generate random numbers in any range: one number, or thousands at once.
- Whole numbers or decimals, with or without repeats
- Presets for 1–10, 1–100, dice, and lottery picks (6 numbers from 1–49)
- Sort the results, copy them, and see your recent draws
Numbers come from your browser's cryptographically secure generator (crypto.getRandomValues) with no modulo bias, so every value in the range is equally likely. That makes it fair for giveaways, raffles, and classroom picks.
